Florida homeowners face some of the highest property insurance premiums in the nation, driven by hurricane exposure, coastal risk factors, and a volatile insurance market. However, there is a powerful financial tool that many homeowners overlook: the substantial insurance discounts available when you install impact windows and impact doors. These discounts are not optional perks offered by generous insurers. They are mandated by Florida law, and every licensed property insurance carrier in the state must offer them.
This guide explains exactly how the discount system works, what inspections you need, how to qualify for the maximum savings, and how to document everything so your insurer applies the full credit to your policy. Whether you are considering new impact-rated products for hurricane protection or simply want to understand the financial return on an upgrade you have already made, you will find everything you need here.

Florida Law Requires Insurance Discounts for Wind Mitigation
Codified in Florida Statute 627.0629, every property insurance company in the state must provide premium discounts to policyholders with wind-resistant construction features. These are not voluntary programs. They are legally mandated.
The legal foundation for wind mitigation insurance discounts in Florida is not a suggestion or guideline. It is codified in Florida Statute 627.0629, which explicitly requires every property insurance company operating in the state to provide premium discounts, credits, or other rate differentials to policyholders who have wind-resistant construction features. This statute has been a part of Florida insurance law since 1994, but it was significantly strengthened in 2005 in the aftermath of the devastating 2004 and 2005 hurricane seasons.
The 2005 legislative session produced sweeping reforms. Lawmakers recognized that homeowners who invested in hurricane-resistant features like impact windows, reinforced roofing, and improved structural connections were reducing risk for insurers and deserved meaningful financial recognition. The updated statute required the Florida Office of Insurance Regulation (OIR) to develop a uniform system for calculating and applying these discounts.
In 2006, the OIR followed through by adopting Rule 69O-170.017, which established the standardized wind mitigation discount framework that is still in use today. This rule created uniform discount categories, defined the inspection process, and set minimum discount percentages that carriers must honor. The result is a system where every Florida homeowner has a legal right to receive insurance premium reductions when their home meets specific wind-resistance criteria.
Importantly, these are not voluntary programs. Every licensed property insurer in Florida, whether a large national carrier or a smaller regional company, must comply. If your home qualifies based on a certified wind mitigation inspection, your insurer is legally obligated to apply the corresponding discounts. Failure to do so is a violation of Florida insurance regulations.
What Is a Wind Mitigation Inspection?
A wind mitigation inspection is a standardized evaluation of your home's ability to resist damage from hurricane-force winds. The inspection is conducted by a licensed inspector, a licensed general contractor, a licensed professional engineer, or a licensed architect using the official OIR form designated as OIR-B1-1802 (commonly referred to as the "1802 form"). This is the only form accepted by Florida insurance companies for the purpose of applying wind mitigation discounts.
The inspection typically takes 30 to 60 minutes and evaluates your home across several critical categories. Each category corresponds to a specific discount tier, and the cumulative effect of strong ratings across all categories can dramatically reduce your windstorm insurance premium.
The inspector evaluates the following areas:
Wind Mitigation Inspection Categories
Roof Shape
Hip roofs, where all sides slope downward toward the walls, perform significantly better in high winds than gable roofs. A hip roof receives a higher discount because its aerodynamic shape reduces wind uplift forces.
Roof Covering
The type and age of your roof covering matter. Roofs installed or replaced after the adoption of the Florida Building Code are presumed to meet current standards and qualify for discounts.
Roof Deck Attachment
How the plywood or OSB sheathing is attached to the roof trusses. Homes with 8d ring-shank nails at 6-inch spacing receive higher discounts than those with staples or wider nail spacing.
Roof-to-Wall Connections
How the roof structure connects to the walls. Hurricane straps that wrap over the truss provide the highest resistance and earn the greatest discount compared to clips or toe-nails.
Secondary Water Resistance (SWR)
An additional layer of protection on the roof deck that prevents water intrusion if the primary roof covering is blown off. Verified SWR earns a significant additional discount.
Opening Protection
This is the category most directly affected by impact windows and doors. It measures how well your windows, doors, skylights, and garage doors resist wind-borne debris.
Opening Protection Categories Explained
The opening protection section of the wind mitigation inspection is where impact windows and doors make the most dramatic difference. The inspector will classify your home into one of four categories based on the level of protection installed across every opening in the building envelope.
How Much Can You Save on Insurance with Impact Windows?
The financial impact of wind mitigation discounts is substantial, particularly in South Florida where windstorm insurance premiums represent a large portion of the total policy cost. While exact savings vary by carrier, location, home value, and the specific combination of mitigation features your home has, the typical range is well-documented.
Typical Percentage Savings
Opening protection alone, specifically achieving a Category A rating with impact windows and doors on all openings, typically saves between 25% and 50% on the wind portion of your insurance premium. The wind portion is the largest component of a Florida homeowner's policy, often representing 60% to 80% of the total premium in coastal areas.
Dollar Amounts in South Florida
For a typical South Florida home, the annual savings from full opening protection range from $1,000 to $3,000 or more per year. Homes in high-wind zones (Miami-Dade, Broward, and Palm Beach counties) with higher insured values tend to see the largest absolute savings. It is not uncommon for homeowners in these areas to save $2,000 to $3,000 annually after achieving a Category A opening protection rating combined with other mitigation features.
Long-Term Cumulative Savings
When you consider the cumulative effect of these savings over 10 to 20 years, the financial picture becomes compelling. A homeowner saving $3,000 per year accumulates $30,000 in savings over 10 years and $60,000 over 20 years. Given that the cost of impact windows and doors for a typical Florida home ranges from $15,000 to $40,000 depending on the size of the home and the products selected, the insurance savings alone can offset a significant portion, and sometimes all, of the installation cost.
It is important to note that savings vary by insurance carrier. Florida allows each insurer to file its own rate schedule with the OIR, so two different companies may offer different discount percentages for the same mitigation features. Shopping your policy after completing mitigation improvements is a recommended strategy to capture the best available rate.
Qualifying for Maximum Insurance Discounts
Earning the highest possible discount requires attention to detail across every aspect of your home's opening protection. The difference between a Category A and Category B rating can mean thousands of dollars per year, and the distinction often comes down to a single overlooked opening.
Products Must Have Florida Product Approval or Miami-Dade NOA
Not just any window or door qualifies. To earn credit on the wind mitigation form, the products installed must carry either a valid Florida Product Approval (searchable on the Florida Building Commission database) or a Miami-Dade County Notice of Acceptance (NOA). These certifications confirm that the product has been tested and approved to meet the large missile impact and cyclic pressure standards required by the Florida Building Code.
Products without a valid Florida Product Approval or Miami-Dade NOA will not count toward your opening protection rating, even if they are marketed as "impact-resistant" or "hurricane-rated." Always verify the approval status of any product before purchasing. Your installer should provide documentation of the product approval numbers for every item installed.
Manufacturer Certificates Are Essential
When you have impact windows and doors installed, request manufacturer certificates for every product. These certificates list the product model, the Florida Product Approval number or Miami-Dade NOA number, the testing standards met, and the design pressure ratings. These documents are critical for the wind mitigation inspector and for your insurance company. Without them, the inspector may not be able to verify that your products meet the required standards, and you could lose your discount eligibility.
The My Safe Florida Home Program
A state-funded initiative offering free wind mitigation inspections and matching grants of up to $10,000 to help homeowners strengthen their homes against hurricanes and reduce insurance costs.
The My Safe Florida Home Program is a state-funded initiative administered by the Florida Department of Financial Services (DFS) that helps homeowners strengthen their homes against hurricanes and reduce insurance costs. The program offers two primary benefits: free wind mitigation inspections and matching grants for mitigation improvements.
Free Wind Mitigation Inspections
Eligible homeowners can receive a free wind mitigation inspection through the program. This inspection uses the same OIR-B1-1802 form used for insurance discounts, so the results can be submitted directly to your insurer. The inspections are conducted by state-approved inspectors and typically include a comprehensive evaluation of your home along with a written report identifying recommended improvements.
Matching Grants Up to $10,000
The program offers matching grants of up to $10,000 to help homeowners pay for qualifying mitigation improvements. The state contributes $2 for every $1 the homeowner spends on qualifying improvements, up to the $10,000 cap. Eligible improvements include impact windows and doors, hurricane shutters, roof upgrades, roof-to-wall connection reinforcement, and secondary water resistance barriers.
Eligibility Requirements
To qualify for the My Safe Florida Home Program, your home must generally meet the following criteria:
- The home must be a site-built, single-family, owner-occupied residential property
- The insured value of the home (dwelling coverage on your policy) must be $700,000 or less
- The home must have an active homeowner's insurance policy
- The home must be located in Florida
- The homeowner must have a completed wind mitigation inspection on file (the free inspection provided by the program satisfies this requirement)
How to Apply
Applications are submitted through the Florida Department of Financial Services website. The process typically involves creating an account, verifying your property eligibility, scheduling a free inspection, receiving your inspection report and improvement recommendations, obtaining quotes for recommended work, submitting your grant application with the quotes, and completing the improvements within the program timeline once approved. Funding availability varies by legislative appropriation, so applying early when a new funding cycle opens is advisable.

Citizens Property Insurance Wind Mitigation Discounts
Published Discount Tables
Citizens makes its wind mitigation discount schedules available publicly. These tables break down discounts by territory (geographic zone), construction type, and each individual mitigation feature. The discounts are applied to the wind portion of the premium and are cumulative, meaning each qualifying feature adds an additional discount layer.
For opening protection specifically, Citizens' discount tables show significant premium reductions for Category A ratings. The exact percentage depends on the wind zone and other factors, but homeowners in the highest wind-risk territories (which include most of Miami-Dade, Broward, and coastal areas throughout the state) see the largest dollar-value reductions.
Specific Mitigation Feature Percentages
While the exact percentages vary by territory and are updated periodically through Citizens' rate filings with the OIR, the general structure awards meaningful discounts across all six inspection categories. Opening protection (Category A) typically carries the single largest discount factor. When combined with a hip roof, hurricane straps, modern roof deck attachment, FBC-compliant roof covering, and secondary water resistance, the total cumulative discount can be dramatic. Citizens policyholders who complete all available mitigation improvements often see their wind premium reduced by half or more.
Documenting Your Impact Windows and Doors for Insurance
Proper documentation is the bridge between having impact products installed and actually receiving the insurance discount. Without the right paperwork, your insurer may not apply the credits even if your home fully qualifies.
Essential Insurance Documentation
NOA & Product Approval Numbers
Every impact window and door should have either a Miami-Dade NOA number or Florida Product Approval (FPA) number. Record these for every product installed.
Installation Permits
All installations require a building permit confirming the work was done to Florida Building Code standards. Keep a copy of the permit and the final inspection approval.
Manufacturer Certificates
Certificates confirming the product model, specifications, testing standards met (ASTM E1886/E1996 or TAS 201/202/203), and approval numbers.
Photographs
Clear photos of every installed product, including product labels with manufacturer name, model, and approval numbers, plus interior and exterior views.
Wind Mitigation Report
The OIR-B1-1802 form completed by your licensed inspector. This is the document your insurer uses to calculate and apply your discounts.
Organized Records File
Keep all documents in a dedicated file: inspection report, NOA/FPA numbers, certificates, permits, contractor info, invoices, and photos. Update when improvements are made.
Combined Mitigation Benefits: Maximizing Total Savings
While impact windows and doors provide the most significant individual discount through the opening protection category, the wind mitigation discount system is cumulative. Each feature on the OIR-B1-1802 form contributes its own discount factor, and the combined effect of multiple strong ratings across all categories can produce extraordinary total premium reductions.
The Full Mitigation Stack
A home that achieves top ratings in every category on the wind mitigation form can see total wind premium discounts approaching 80% to 90%. The full mitigation stack includes:
- Impact windows and doors on all openings (Category A) — the single largest discount factor for opening protection
- Hip roof geometry — additional discount for the aerodynamically superior roof shape
- Modern roof-to-wall connections (hurricane straps) — significant discount for wrap-around metal connectors
- Strong roof deck attachment — discount for 8d nails at 6-inch spacing or equivalent
- FBC-compliant roof covering — discount for roof coverings installed to current Florida Building Code standards
- Secondary water resistance barrier — additional discount for peel-and-stick or equivalent SWR on the roof deck
The interaction between these features is powerful. For example, a home with impact windows (Category A) but a gable roof and toe-nailed connections will still save significantly on opening protection, but will miss the additional discounts available for roof shape and connections. Conversely, a home with a hip roof, hurricane straps, and SWR but no opening protection (Category N) misses out on the single largest discount category.
The ideal strategy is to address all categories systematically. When planning a hurricane protection upgrade, consider the full picture: impact windows and doors for opening protection, roof improvements for structural integrity, and connection upgrades where accessible. The combined investment often produces insurance savings that exceed any single improvement.
Florida's Insurance Crisis: Why Mitigation Discounts Matter More Than Ever
Florida homeowners now pay the highest average property insurance premiums in the nation. As base premiums increase, the percentage-based discounts for wind mitigation become more valuable in absolute dollar terms.
Florida's property insurance market has experienced significant upheaval in recent years. The state has seen a pattern of rising premiums, carrier insolvencies, and market withdrawals that has left many homeowners facing dramatically higher costs for coverage, when they can find coverage at all. In this environment, wind mitigation discounts are more valuable than they have ever been.
Rising Premiums
Florida homeowners now pay the highest average property insurance premiums in the nation. Multiple factors drive this trend, including hurricane exposure, reinsurance costs, litigation expenses, and fraud losses. As base premiums increase, the percentage-based discounts for wind mitigation become more valuable in absolute dollar terms. A 30% discount on a $2,000 premium saves $600, but a 30% discount on a $6,000 premium saves $1,800. As premiums climb, the financial return on mitigation investments grows proportionally.
Carrier Insolvencies and Market Instability
Several Florida-based property insurance companies have been declared insolvent or placed into receivership in recent years. When a carrier fails, policyholders must find new coverage, often at significantly higher rates. Homeowners with strong wind mitigation features and documentation are better positioned to secure competitive rates with remaining carriers because they represent lower risk. A well-documented wind mitigation report demonstrating Category A opening protection, hurricane straps, and other features makes your home a more attractive prospect for insurers.
Mitigation as a Financial Strategy
In the current market, investing in wind mitigation is not just about hurricane protection. It is a strategic financial decision. The annual savings compound year after year, and the products themselves add value to your home. Impact windows and doors increase property values, improve energy efficiency, reduce noise, and enhance security, all while generating ongoing insurance savings. When evaluated as a long-term financial investment, few home improvements offer a comparable combination of tangible benefits and financial return.
Getting Started: Your Step-by-Step Guide to Insurance Savings
If you are ready to reduce your Florida insurance premiums through wind mitigation, follow this step-by-step process to ensure you capture the maximum available discounts.
Get a wind mitigation inspection
Schedule an inspection with a licensed inspector, contractor, engineer, or architect who uses the OIR-B1-1802 form. If you qualify for the My Safe Florida Home Program, you can get this inspection for free. The inspection will establish your current baseline and identify exactly which features earn discounts and which areas need improvement.
Identify unprotected openings and weak points
Review the inspection report carefully. Note which openings lack impact-rated protection and which structural features (roof connections, deck attachment, SWR) fall short of the top rating. Pay special attention to the opening protection category since this is where impact windows and doors make the biggest difference.
Get quotes for impact windows and doors
Contact qualified installers to get estimates for protecting all remaining openings. Make sure the products quoted carry valid Florida Product Approvals or Miami-Dade NOAs. Compare product options and review our cost guide to understand typical pricing ranges.
Install impact-rated products on all openings
Work with a licensed contractor to install impact windows and impact doors on every opening. Ensure the installation is permitted and inspected by the local building department. Collect all manufacturer certificates, NOA numbers, product approval numbers, and photographs during the installation process.
Get a new wind mitigation inspection
After installation is complete, schedule a new wind mitigation inspection to document the improvements. The updated OIR-B1-1802 form will reflect your new Category A opening protection rating and any other improvements you made.
Submit the updated inspection to your insurer
Send the new wind mitigation inspection report to your insurance company and request that they apply the updated discounts to your policy. Ask for a revised premium statement showing the new discounts. If your current carrier does not offer competitive rates with the new mitigation credits, shop your policy with other carriers. The wind mitigation report is portable and can be submitted to any Florida insurer.
The entire process, from initial inspection to receiving your updated premium, typically takes 4 to 12 weeks depending on the scope of the installation work. The insurance savings begin as soon as your carrier applies the updated wind mitigation credits to your policy.
Florida law is on your side. The discounts exist, they are mandatory, and they are significant. The only question is whether you take the steps to qualify for them. For most Florida homeowners, particularly those in high-wind zones like South Florida, the investment in impact windows and doors pays for itself through insurance savings alone, while also providing the peace of mind that comes with genuine hurricane protection.
